Thank you, chopedogg88, for the quick reply. Unfortunately, pressing and holding on the lock doesn't appear to do anything. Is that an OS3 feature? I tried pressing and holding on the "security" icon as well as on the individual locks (as shown in my screen image above). Am I doing something wrong?
As a reminder, I'm running OS2, and the iOS app version is 2.10.21.195 (which I believe is the most recent OS2 app).
Any other ideas?
